[70] Philip Salmuth (_Observationes Medicæ_, Centuria II, no. 63) in the seventeenth century recorded a case in which a young girl of noble birth (whose sister was fond of eating chalk, cinnamon, and cloves) experienced extreme pleasure in smelling old books. It would appear, however, that in this case the fascination lay not so much in the odor of the leather as in the mouldy odor of worm-eaten books; "_fætore veterum liborum, a blattis et tineis exesorum, situque prorsus corruptorum_" are Salmuth's words.

[74] In this connection I may quote the remark of the writer of a thoughtful article in the _Journal of Psychological Medicine_, 1851: "The use of scents, especially those allied to the musky, is one of the luxuries of women, and in some constitutions cannot be indulged without some danger to the morals, by the excitement to the ovaria which results. And although less potent as aphrodisiacs in their action on the sexual system of women than of men, we have reason to think that they cannot be used to excess with impunity by most."

[77] In Normandy the _Chenopodium_, it is said, is called "conio," and in Italy erba connina (con, cunnus), on account of its vulvar odor. The attraction of dogs to this plant has been noted. In the same way cats are irresistibly attracted to preparations of valerian because their own urine contains valerianic acid.
